Haynes Manual Build a Robot

[Theo]

My Sabretooth ESC (thanks again Dave) is a good few years old now, and going as strong as ever.

It also helped that my robot was only 4.2kg, I never went full throttle because it would swerve violently, and the wheels had virtually no grip and no opportunity to draw those amps. But the thing worked and survived, and didn't need any padding either (barring velcro).



Your issue isn't with the ESC, it's with the receiver. The same thing happened a few days before Gloucester. Powered it up, turned the Tx off as a test. Kept moving. The failsafe feature doesn't seem to be on the 2x12, it may be on the 2x5 (the switch diagrams are different; I was using the 2x5 one for my 2x12). Regardless, I had to buy a whole new radio set for it to work, Hitec Optic 5: given me no problems so far.

If I have a Dx6i transmitter what receiver would you suggest?
